Bumpiness along the flight

Takeoff on the left, landing on the right. The higher the line, the bumpier the air the forecast expects at that moment.

Where, and why

The flight split into stretches: how bumpy each is forecast to be, and what causes it.

Cruise0m – 2h 35mSmooth

Nothing significant forecast here.

At cruise the air is thin and cold, and most of it is calm. The bumps up here come from the jet stream, a band of fast wind whose edges stir the air, or from waves set off by mountains far below. This forecast shows where those edges are.

Thunderstorms near the route

Between 13m and 1h 21m into the flight the forecast has a few thunderstorms, the nearest about 50 km from the planned line.

The ride line can stay calm with storms nearby. It follows the planned track at cruise height, above most storm tops. Pilots don't fly through storms: the weather radar in the nose shows each one, and the rule is to stay at least 20 nautical miles (about 37 km) away. Usually that means a detour of a few minutes.

The ride line stays calm here because the route as planned keeps its distance from them.

Bigger and heavier aircraft are moved less by the same patch of air, and every airliner is designed for much stronger turbulence than it will meet.

What each level feels like

Smooth
Calm air. Nothing to notice beyond the hum of the engines.
Light
Gentle ripples and the odd dip. Drinks stay put, and walking to the toilet is fine.
Moderate
Clear bumps. Drinks may slosh and the belt sign comes on. Uncomfortable, but the pilots stay in full control.
Severe
Strong jolts, and loose items can move. This is rare, and it's why the belt sign exists. Crews slow down and change altitude to get out of it.

How this forecast is made

The planned route is sampled from gate to gate at the altitude the aircraft flies, through 3 independent global weather models, and corrected with turbulence reports radioed in by pilots in the last few hours. Each new model run replaces the forecast; nothing here is a guess from the airline's history.

The independent weather models behind this forecast agree on this ride.

Why turbulence isn't dangerous

Aircraft are designed for much worse.

Airliners are tested to loads well beyond anything turbulence produces. The wings are meant to flex, so seeing them move is normal.

Crews know where it is.

Your crew has forecasts like this one, live reports from other pilots and their own weather radar, and they change altitude to stay out of bumpy air.

Keep your belt on.

Almost all turbulence injuries happen to people who are standing or not buckled in. Seated with your belt on, turbulence is uncomfortable but not dangerous.

Is turbulence dangerous on TR621?

Turbulence is uncomfortable, not dangerous to the aircraft. Airliners are certified for loads far beyond anything turbulence produces, and crews plan around the bumpy patches with the same kind of forecast as this one. Injuries are almost always to people who were standing or unbuckled, so keep your seatbelt fastened whenever you're seated.

How accurate is this turbulence forecast?

It is a forecast, so it is best within a day or so of departure and improves with every model run. The bumpy patches it finds are usually in the right place, but their timing can shift by a few minutes and the crew may change altitude to avoid them, so the ride you get is often smoother than the forecast.
